PHONOGPJAPH STARTING AND STOPPING DEVICE.

Application filed May 21, 1925.

To all whom it may concern Be it known that I, LOUIS JURENKA, a citizen of Czechoslovakia, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Phonograph Starting and Stopping Device, of which the following is a full, clear, and exact description.

This invention relates to an automatic control for talking machines and particularly to an improved starting device for releasing the machine at a. certain time.

An object of the invention is to provide a starting and stopping device for talking machines which includes an automatically operated mechanism released by an alarm clock whereby the machine will function at the time of operation of the clock, the automatic release co-acting with an automatic stop for stopping the machine as soon as the record has been completed.

Another object, more specifically, is to provide an alarm clock and arrange the same in the body of a talking machine and so connect the same that the talking machine may be automatically started by the alarm mechanism of the clock.

In the accompanying drawing- Figure 1 is a perspective view of a talking machine with certain parts broken away, said View, illustrating an embodiment of the invention connected to the talking ma chine.

Figure 2 is an enlarged fragmentary sectional view through part of the structure shown in Figure 1 illustrating more in de tail the releasing and starting mechanism.

Referring to the accompanying drawing by numerals, 1 indicates a talking machine of any desired kind, said machine being provided with the usual table 2 for receiving the record. Oo-acting with the table 2 is the usual stylus 3, sound box 4: and associated parts found in talking machines now on the market. In addition to these members, an auton atic stop 5 of any desired construction is provided in the talking machine 1 and is adapted to stop the opera tion of the talking machine when a record has been completed. The various structures just described form no part of the in vention specifically and only in combination with the starting mechanism herein after fully described.

Serial No. 31,902.

As indicated particularly in Figure 1, the casing of the talking machine 1 is cut away at 6 and 7 and in the opening provided at 6 there is mounted an ordinary alarm clock 8. A shaft 9 is connected to the winding arher of the alarm clock 8, said shaft extend ing through a covering plate 10 arranged over the aperture 7 so that the winding knob or thumb member 11 may be arranged e2;- teriorly of the talking machine. A shaft 12 is connected to the winding mechanism for the main spring of the clock, said shaft extending through plate 10 so that the knob 13 may be arranged exteriorly of the talk ing machine. An arm 14 is rigidly secured to shaft 9 and has a cord 15 connected to the outer end thereof, said cord passing upwardly and over a grooved pulley 16 rotatably mounted on pin 17. The position of the pulley wheel 16 is such that the upper end is near the under surface of the table 2. A spring 18 is connected to the end of a cable or cord 15 and to a bracket 19 whereby whenever the arm 14 will permit, spring 18 will pull the cord 15 as the spring 18 is always under tension. A shoe 20 of leather, rubber or other material, is carried by the cord 15 near the point where the same is connected-with the spring 18. This shoe is so positioned that when the alarm mechanism of the clock 8 is set, the shoe will press rather tightly against the under surface of the table 2 and thereby prevent the rotation thereof even if the same has been released.

When the alarm mechanism of the clock 8 has been released or goes off, shaft 9 will rotate and swing arm 14.- upwardly. This will release the cord 15 and immedi ately spring 18 will begin to pull the cord over the pulley wheel 16 and the shoe 20 away from the table 2. As the shoe 20 is in rather firm contact with the table 2, this pulling action will give the table 2 a start so that the spring of the talking machine may cause the table 2 to quickly reach its proper speed. fter the record has been played, the automatic stop 5 automatically functions to stop the machine. It is evident that the clock 8 could be set to cause the talking machine to begin to operate at any time, as for instance, at meal times or in the morning at the time it is desired to rise.
